(Cl. 226-127) i(GxfalltedunderTitle 35, U.`S.'Code (1952),'sec. 266) 'lhe invention described herein, if patented, .mayp'be manufactured and used by 4or for .the Government for governmental purposes, without .the .payment to me of .any royalty thereon.

'The present invention relates -to :nozzles for udispensing `gasoline and other Zliquids and has .for its `generalobject; :to provide an 'integrated construction of nozzle -w'hich is `automatically opened when `the nozzle is `placed 'ina .re-

ceptale to be `filled, .andautomatically :closed when the .liquid reaches a predetermined level 'in the 'receptacle 'being filled.

.A further object of the invention .resides in the vprovision of an automatic nozzlewhichis composedof only ,affewfmova'ble elements and which'elements .are .of strong .and sturdy construction.

.A still further object of the invention-consists .in the construction of an `automatic nozzle in which the parts .are soarranged as toreduce wear and l.tear to aminimum.

Another object of the .invention consistsintheprovision .of an .automatic Anozzle including an .articulated sleeve valve .and poppet valve each 'of whichis automatically .operated to control .the ow .of'liquid through the nozzle.

Other objects and advantages of the invention will be apparent from the following description .takenin .con- .nection .with ythe accompanying drawings,.in which,

:Figure l is a longitudinal sectional view .through .the .improved .dispensing nozzle showing :the .same in closed position;

Figure '2 is a ,plan v'iew thereof;

AvFigure 3 is a longitudinal :sectional View similar .to'Figure 1 but showing the sleeve valve in open position and the float .valveclosed in dottedfoutlinegand Figures 4, 5 and 6 are transverse sectional views taken on the lines 'l-i1, 53--5 Qand6-6,rrespect1vely, of Figfure 3.

M'ore specifically, the numeral .1 indicates -the rbody portion .ofthe dispensing .nozzle ,provided with .a `substant`ially\ cylindrical interior `2 which is .open at its upper end .and adapted to 'be closed'by a threaded closure '3 which permits access `to the 'interior o'f the .body portion. 'The casing is provided with a nipple '4f'for the reception of one end of a hose lextending .from the source of supply, .and an.inlet opening S to the cylindrical interior-:tube 0f the casing.

Slidably mounted in the interior of the casing 1 is a sleeve valve 6 provided with an annular series of openings 7 adapted to cooperate with the inlet 5 when the sleeve valve is in open position, and also with an annular groove 8 formed in the body portion of the nozzle intermediate its end. The lower end of the sleeve valve 6 is provided with a tubular extension or nozzle tube 1 which is shown as integrally formed with the sleeve valve and is movable therewith as a unit.

The cylindrical interior of the body portion of the nozzle is provided, in the present illustration, with upper and lower annular grooves 9 and 10 connected by a vertical passage 11 formed in an enlargement or protuberance 11 of the body portion of the nozzle. The sleeve valve 6 is guided in its vertical movement at the upper end of the body portion of the nozzle by means of a bushing 12 provided with an inwardly directed gasket 13 for sealing the same, and the lower end of the sleeve valve has its bearing on the inner face of the body portion itself, such inner face being provided with inwardly dirlected seats for gaskets 14 and 15 for sealing oi the va ve.

The bushing 12 extends to the upper end of the interior Aofthe mozzle casing and .is lprovided .With an annular seriesof ports 1,6 icommunicating with .the recess 9 .and :the vertical .passageway 11. Likewise, the .lower portion of athe :sleeve fva'lve is provided with an .annular series lof ports -17 which communicate with the :annu- -lar groove 16 fin the :lower Aeportion :of ,the `body -of the nozzle and with the ilower end of the vertic-al passageway Adjacent its upper vend .the -sleeve valve y6 -isprovided with a downwardly =directed `Valve lseat 18 for a purpose to be hereinafterfdescribed.

iEngaging the `upperedg'e v.of :thefring in which the'valve eeat i3 -is formed is a compression spring :19 having its upper end seated againstfthe undersurfacevof 'fthe-closure 3. This spring, `of course, servesto bias the .sleeve valve Y6 downwardly, andsuchdownward movement is limited by the engagement-of algasketwithits.seat 21 formed in the body portion yof .the lnozzle. :Upward -movement :of the sleeve valve is .limited .by ia shoulder .22 formed on the external wall of the valve and adapted to kengage the lower ,endtofbushing 12, .and .the length of the sleeve lvalve is `such .that when-moved .to .its upper position its vupper end :will lie -ilush 1with theloweriedgeof the annular seriesrot ports ,v1-6, as-indicated'infFigure 3.

vvFrom :the structure so far described, it will be apparent -that .when the sleevefvalve -6 -is moved to .its closed Iposition fby-rhespring ;-19;,-the inlet passage 5 'is closed as indicated :in .Figure .-l, -and the :lower endof -the vertical A.passage al is yalso closed. l@n..the-.otherl:rand, wherrthe sleeve vali/.e6 is moved .upwardly .against the 5pressure `of .-spr-ing ,19, 'in a .manner .to be rrhereinafter described, the series -.:of lports J7 will ,align with the Lannular groove 8 andthe :inletS'so .as .toperrnit-.the passagefof liquid up- -wardly I.through -the :sleeve valve ito lthe annular .series of :por-ts l16, grooves .9, yerticahpassage 11, icirculargroove 1).andzannularseries-.of -ports d'7, and .thence .to the .tubu- .larextension or nozzletubel.

Adjustably .mounted .on the exterior `of -the knozzle section .-1 Yis `a vband curing-23 which `,is yadapted to .engage .a wall of a -receptacle to .be .-tilled v,and into which the nozzle tube 21 `is projected. .Aportion of :such .a :receptacle is indicated in Figure 3.

It will be apparent, of course, that by adjusting the vertical position of the ring 23 along the length of the tube 1', the amount of fluid allowed to enter a receptacle may be varied as desired.

The operation of the various parts have been described in connection with the description of the structure and need not be repeated, except to the extent of pointing out that I have provided an integrated construction formed of only a few movable parts; that such parts are all enclosed within the structural features of the nozzle itself and are therefore guarded against rough usage; that the movable parts are so designed and articulated as to reduce wear and tear to a minimum; and yet this simplified construction produces an automatic dispensing nozzle which is automatically opened for discharge when the nozzle tube 1 is projected into a receptacle to be filled, and it is automatically closed when the level of the liquid entering the receptacle reaches a predetermined height.

In accordance with the patent statutes, I have described what I now consider to be the preferred form of the automatic dispensing nozzle, but since various changes may be made in structural details without departing from the spirit of the invention, it is intended that all such variations be included within the scope of the appended claims.
